Sharp Presents a New Generation of Its 4W & 7W Mini Zenigata LEDs

The new product generation is again based on a small plate made of technical ceramics (aluminium oxide Al2O3) with the dimensions 15mm x 12mm x 1.6mm. Efficiency was able to be improved by up to 11% due to technical progress. The new generation of 4 and 7W arrays is characterised by four properties: Compact, light, economical and noticeably brighter than before.

Depending on the module, the new types provide a luminous flux of up to (typically) 585 lumens, with a light efficiency of up to 91lm/W at nominal operating data, a high CRI value of 82, and a long service life of 40,000 hours at an operating temperature of up to 90°C.

The new generation of 4W arrays has a forward voltage of 9.6V with a constant current of 400mA, whereas the 7W arrays have a voltage of 12.3V with a current of 520mA. The 4W arrays, however, can also be operated with an increased constant current of 500mA, thus making them capable of reaching a luminous flux of up to 400lm. With the 7W arrays, a luminous flux of up to 830 lumens can be reached, if they are operated with a current of 680mA. The colour temperatures of the new white-light LED arrays range from 2,700 to 6,500 Kelvin’s, with the shades "Natural White", "Warm White" and "Pure White".

The very smooth surface of the ceramic underside of the Mini Zenigata makes it possible to attach the modules easily and safely on a suitable heat sink, in order to achieve efficient heat dissipation.
